Fallout Shelter is a free-to-play simulation game developed and published by Bethesda. Part of the Fallout series, it was released for the Nintendo Switch in June 2018. The game tasks the player with building and effectively managing their own Vault, a fallout shelter.


In Fallout Shelter, players build and manage their own Vault as an Overseer – the leader and coordinator of their Vault. Players guide and direct the citizens of the Vault, and need to keep them happy through meeting their needs such as power, food, and water. They rescue dwellers from the wasteland and assign them to different resource-generating buildings in the Vault, using the SPECIAL statistics system from the other Fallout games. Each character's SPECIAL profile affects their ability to generate different resources, and their statistics can be increased by training them in rooms devoted to each stat. The dwellers can level up over time, increasing their health, and can be given new items and weapons to help with various tasks. The number of dwellers can be increased by waiting for new dwellers from the wasteland to arrive or by pairing a male and a female dweller in living quarters to produce babies.

Balancing resources such as food, water, and power is an important aspect of the game. Many different rooms can be built in the Vault, providing different items or stat bonuses. Players are not required to spend money in order to accelerate long timers or processes, instead having the option to instantly complete tasks at the risk of catastrophic failures – such as fires or "radroach" infestations. Players are sometimes rewarded with lunchboxes that contain rewards, such as items or resources, which can be purchased separately through microtransactions.
